"The most powerfully growing products," he says, "do three things at once: they make you look smart to the people you invite. They give real value to you when the people you invite join. And they give real value to the people you've invited once they sign up."
The least important attribute they look for is "expertise." Said Bock: "If you take somebody who has high cognitive ability, is innately curious, willing to learn and has emergent leadership skills, and you hire them as an H.R. person or finance person, and they have no content knowledge, and you compare them with someone who's been doing just one thing and is a world expert, the expert will go: 'I've seen this 100 times before; here's what you do.' " Most of the time the nonexpert will come up with the same answer, added Bock, "because most of the time it's not that hard." Sure, once in a while they will mess it up, he said, but once in a while they'll also come up with an answer that is totally new. And there is huge value in that.
